Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a coupling device for farmland soil cultivation and fertilizer spraying. Background Art

[0002] In the process of corn planting, soiling is an important agricultural management measure. The purpose of soiling is to help corn plants grow better, prevent lodging, and promote the development of the root system. Through soiling, the contact area between the soil and the corn roots can be increased, and the water and fertilizer retention of the soil can be improved, which is beneficial to the growth and development of corn. Soiling also helps to control the growth of weeds, reduce the competition of weeds on corn, and improve the yield and quality of corn.

[0003] Publication No.: CN104255095B The integrated machine for tillage, fertilization, soiling and root cutting of corn with high ground clearance can realize the mechanized integrated operation of tillage, topdressing, soiling, root cutting and other measures, simplify the operation links, improve the operation efficiency, and help improve the level of corn production management; through tillage, topdressing and soiling, the soil conditions and nutritional requirements for corn growth are improved, and the lodging resistance of corn is improved; through synchronous root cutting operations, the growth and development of corn can be regulated, and the relationship between the nutritional growth and reproductive growth of corn with good water, heat and nutritional conditions can be coordinated, which is conducive to high-yield corn production; the high ground clearance setting realizes the passability and practical feasibility of operations in the early and middle stages of corn growth, and can prevent damage to corn during operations.

[0004] In the related art, it is generally best to carry out soiling of corn before the small trumpet mouth to the large trumpet mouth. Too early soiling will inhibit the generation and growth of corn node roots, which is not conducive to the formation of a strong root system and affects the anti-lodging ability of corn. The period from the small trumpet mouth to the large trumpet mouth of corn is usually the critical period of fertilizer requirement and the maximum efficiency period of corn. During this period, the absolute and relative amount of nutrients required by corn is the largest, the absorption rate is also the fastest, and the effect of fertilizer is the greatest. At this time, the fertilizer application amount is appropriate, and the corn yield increase effect is the best. In addition, corn is easily attacked by pests and diseases during the trumpet mouth period. Pests will eat the heart leaf part of corn. After the damaged leaves grow out and unfold, the wind is prone to stem breakage. When the device is in use, although corn can be soiled and fertilized, the soil on the surface of the corn root system is floating soil after soiling the corn. When corn is in the trumpet mouth period, it is in summer and there is heavy rain. The floating soil and fertilizer on the root surface are easily washed away by rain along the ditch produced by soiling, thereby causing the loss of soil and fertilizer, thereby affecting the growth of corn.

[0005] Therefore, it is necessary to provide a coupling device for farmland soil cultivation and fertilizer spraying to solve the above technical problems. Summary of the invention

The bottoms of the four connecting rods 42 are fixedly provided with a second rotating seat 45, and the inner sides of the four second rotating seats 45 are rotatably connected to telescopic rods 46. The surfaces of the four telescopic rods 46 are slidably connected to telescopic sleeves 47, and the inner sides of the four telescopic sleeves 47 are provided with telescopic springs 48. The bottoms of the four telescopic sleeves 47 are rotatably connected to the surface of the movable bracket 41, and two movable springs 49 are fixedly provided on the inner side of the top of the movable bracket 41.

[0054] Please combine Figure 4 , Figure 5 and Figure 6 : After the corn roots are covered with soil by the tilling wheel 32, the root soil can be scraped flat by the pressing plate 44, so that the soil at the corn roots forms a trapezoidal shape. When the movable bracket 41 moves downward, the two pressing plates 44 are pressed downward by the connecting rods 42 on both sides. The two pressing plates 44 press downward and compact the soil near the corn roots. When the movable bracket 41 moves up and down reciprocatingly, the two pressing plates 44 can be reciprocated at a certain frequency. By setting the telescopic rod 46 and the telescopic spring 48, the connecting rod 42 and the pressing plate 44 can be effectively supported.

[0055] The tilling wheel 32 is composed of a digging wheel and a ridging knife, and the front and rear positions of the first belt pulley 35 and the second belt pulley 36 are on the same parallel line.

[0056] The suppressing mechanism 4 has two groups, which are respectively arranged on the rear sides of the two tilling wheels 32. A raised portion is arranged on the front side of the top of the movable bracket 41. Through grooves are opened on the inner side of the top and the inner side of the bottom of the movable bracket 41. The two suppressing plates 44 are arranged in a V-shape.

[0057] In this embodiment, compared with the existing corn soil-raising device, the present invention turns up the soil between the corn plants through the rotation of the soil-turning wheel 32, and raises the soil to the corn root position, and then through the setting of the pressing plate 44, the soil at the corn root position can be scraped flat, so that the soil of the corn root part forms a trapezoidal shape, which is convenient for rainwater to flow smoothly, and the two pressing plates 44 move to both sides at a certain frequency through the up and down reciprocating movement of the movable bracket 41 under the action of the connecting rod 42, so that the soil of the corn root part is compacted to prevent the soil of the corn root part from being too loose when it rains and being washed away by rainwater, thereby causing ineffective soil-raising of the corn, and the compacted soil can completely cover the weeds near the corn root system, making it impossible for the weeds to breathe and photosynthesize, thereby controlling the growth of the weeds and reducing the competition of the weeds on the corn. The soil that has been pressed after the corn soil-raising can also improve the water retention and fertilizer retention of the soil, thereby promoting the growth of the corn root system, and then increasing the corn yield.

[0058] Second embodiment:

[0059] See also Figures 8 to 11 The bottom of the mounting frame 1 is connected to a fertilizer mechanism 5, and the fertilizer mechanism 5 includes two discharge pipes 51 connected to the bottom of the mounting frame 1, and the inner sides of the two discharge pipes 51 are laterally connected to a rotating shaft 52, and two discharge impellers 53 are fixed on the surface of the rotating shaft 52 and located on the inner sides of the two discharge pipes 51, and the two ends of the rotating shaft 52 are rotatably connected to the inner side of the connecting frame 2, and a driving motor 54 for driving the rotating shaft 52 to rotate is provided on the right side of the connecting frame 2, and a support seat 55 is provided at the bottom of the driving motor 54, and the left side of the support seat 55 is fixedly connected to the right side of the connecting frame 2;

[0060] Please combine Figure 8 and Fig. 9 : Start the driving motor 54, and the rotation of the driving motor 54 drives the rotating shaft 52 to rotate, and the rotation of the rotating shaft 52 drives the discharging impeller 53 to rotate, and the rotation of the discharging impeller 53 causes the fertilizer to evenly fall from the discharging pipe 51 to the ground, thereby fertilizing the corn;

[0061] Preferably, the discharge pipe 51 is externally connected to a plastic elbow when in use, and the discharge position of the fertilizer is located in front of the tilling wheel 32 by adjusting the plastic elbow. After the tilling wheel 32 turns, the fertilizer can be mixed in the soil, and the soil mixed with the fertilizer is turned to the root part of the corn by the tilling wheel 32, and the soil is cultivated and fertilized at the root part of the corn. After the two cooperate with each other, the fertilizer retention effect of the soil can be improved;

[0062] Furthermore, when the driving motor 54 drives the rotating shaft 52 to rotate, the rotating shaft 52 drives the two second pulleys 36 to rotate, and the two second pulleys 36 further drive the two first pulleys 35 and the tiller wheel 32 to rotate through the first belt 37 .

[0063] A crushing mechanism 6 is provided on the top of the mounting frame 1. The crushing mechanism 6 includes two fertilizer hoppers 61 fixedly provided on both sides of the top of the mounting frame 1. The inner sides of the two fertilizer hoppers 61 are both connected with crushing rollers 62 for transverse rotation. A third belt pulley 63 is fixedly provided on one end of the two crushing rollers 62 and on one side of the two fertilizer hoppers 61. A fourth belt pulley 64 is fixedly provided on the surfaces of both ends of the rotating shaft 52.

[0064] Please combine Fig.10 and Fig.11 When the driving motor 54 drives the rotating shaft 52 to rotate, the rotating shaft 52 will simultaneously drive the fourth pulleys 64 at both ends to rotate, and the two fourth pulleys 64 will drive the two third pulleys 63 to rotate through the second belt 65, and the rotation of the two third pulleys 63 will drive the two crushing rollers 62 to rotate, and the agglomerated fertilizers will be crushed by the rotation of the two crushing rollers 62 to prevent the block fertilizers from clogging the discharge pipe 51 and causing the problem of uneven fertilizer application.

[0065] The two second belt pulleys 36 are fixedly connected to the rotating shaft 52 , and a through groove for cooperating with the two first belts 37 is formed on the inner side of the connecting frame 2 .

[0066] In this embodiment, the rotation of the driving motor 54 drives the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, it drives the second pulley 36, the discharging impeller 53 and the fourth pulley 64 to rotate. The rotation of the discharging impeller 53 drives the fertilizer to be discharged evenly. When the fourth pulley 64 rotates, the third pulley 63 and the crushing roller 62 are driven to rotate through the second belt 65, so that the crushing roller 62 can be used to crush the agglomerated fertilizer, thereby ensuring that the fertilizer can fall evenly during fertilization.

[0067] Third embodiment:

[0068] See also Figures 14 to 16 A medicine spraying mechanism 7 is provided on the top of the mounting frame 1, and the medicine spraying mechanism 7 includes a medicine box 71 provided on the top of the mounting frame 1. A medicine spraying frame 72 is fixedly provided on the back of the mounting frame 1. A medicine outlet pipe 73 is vertically provided on the inner side of the medicine spraying frame 72. A water pump 74 is provided on the top of the medicine spraying frame 72. The top of the medicine outlet pipe 73 is connected to the water pump 74, and the water pump 74 is connected to the medicine box 71. A valve 75 is provided on the surface of the bottom end of the medicine outlet pipe 73. A tension spring 76 is provided on the inner side of the valve 75. A connecting seat 77 is provided on the top of the tension spring 76. The back of the connecting seat 77 is fixedly connected to the front of the medicine spraying frame 72.

[0069] Please combine Fig.12 and Fig.13 : Turn on the water pump 74, and press the valve 75 downward, the tension spring 76 is further stretched, the water pump 74 extracts the medicine from the medicine box 71, and pumps the medicine into the medicine outlet pipe 73. After the valve 75 is pressed down, the medicine can flow from the medicine outlet pipe 73 into the medicine spraying pipe 84. Release the valve 75, and the valve 75 can be automatically closed by the retraction of the tension spring 76, so that the medicine outlet pipe 73 stops delivering the medicine to the medicine spraying pipe 84;

[0070] The top of the movable bracket 41 is slidably connected to the inner side of the spray rack 72 , the bottom of the movable spring 49 is fixedly connected to the bottom of the inner side of the spray rack 72 , and a through groove for use with the movable bracket 41 is provided on the inner side of the spray rack 72 .

[0071] A flip mechanism 8 is provided on the top of the spraying frame 72, and the flip mechanism 8 includes two hydraulic rods 81 provided on the top of the spraying frame 72, and the output ends of the two hydraulic rods 81 are fixedly provided with connecting plates 82, and the two connecting plates 82 are rotatably connected to the opposite sides thereof with a transverse plate 83, and a spraying pipe 84 is fixedly provided at the bottom of the transverse plate 83, and a spray head 85 is connected to the top of the spraying pipe 84 and located on the inner side of the transverse plate 83, and gears 86 are fixedly connected to the two sides of the transverse plate 83 and located on the separated sides of the two connecting plates 82, and guide frames 87 are fixedly provided on the separated sides of the two gears 86, and protective frames 88 are fixedly provided on the two sides of the spraying frame 72, and gear plates 89 are fixedly provided on the front sides of the two protective frames 88, and the medicine outlet pipe 73 is connected to the spraying pipe 84;

[0072] Please combine Figures 14 to 16: Start the two hydraulic rods 81, the two hydraulic rods 81 extend downward, and the two connecting plates 82 are driven to move downward by the extension of the two hydraulic rods 81. When the two connecting plates 82 move, they will drive the two gears 86 to move at the same time. When the two gears 86 contact the two gear plates 89 respectively, the two gears 86 will drive the cross plate 83 and the guide frame 87 to flip. The flip of the cross plate 83 drives the spraying pipe 84 and the spray head 85 to flip, so that the spray head 85 can face downward. At this time, open the water pump 74 and the valve 75, so that the medicine can be sprayed from the spray head 85, and then the heart leaf part of the corn can be sprayed;

[0073] Furthermore, when the two hydraulic rods 81 extend downward, the two gears 86 drive the horizontal plate 83 to flip, and the horizontal plate 83 moves downward through the continuous extension of the hydraulic rods 81. When the horizontal plate 83 moves downward, it touches the valve 75 and presses the valve 75 downward. At this time, the water pump 74 is turned on, so that the medicine can be transported from the medicine outlet pipe 73 to the medicine spraying pipe 84 and sprayed through the nozzle 85. When the two hydraulic rods 81 retract and drive the horizontal plate 83 to move upward, the valve 75 can be automatically reset by the retraction of the tension spring 76, and the nozzle 85 stops spraying medicine.

[0074] Furthermore, when the two hydraulic rods 81 extend downward and drive the cross plate 83 to move downward, the cross plate 83 will press the two mobile brackets 41 downward during the movement. The two mobile brackets 41 are pressed downward and the pressure plate 44 is pressed to both sides under the action of the connecting rod 42, thereby compacting the soil after soiling. When the two hydraulic rods 81 retract upward and drive the cross plate 83 to move upward, the telescopic spring 48 is set to make the mobile bracket 41 slide upward on the inner side of the spray rack 72, and the pressure state of the pressure plate 44 is cancelled under the action of the connecting rod 42. The cross plate 83 moves back and forth up and down, so that the pressure plate 44 compacts the soil after soiling at a certain frequency.

[0075] Traction frames 9 are fixedly provided on both sides of the top of the connecting frame 2 .

[0076] In this embodiment, the two hydraulic rods 81 are started, and the two hydraulic rods 81 drive the two connecting plates 82 to move downward. During the movement of the two connecting plates 82, the two gears 86 are driven to move downward. When the two gears 86 move to the position of the gear plate 89, the gear plate 89 causes the two gears 86 to drive the cross plate 83 and the guide frame 87 to flip, so that the nozzle 85 faces downward. When the hydraulic rods 81 continue to extend downward and drive the flipped cross plate 83 to move downward, the cross plate 83 presses down the valve 75 during the movement. Turn on the water pump 74, and the water pump 74 will pump the medicine through the medicine outlet pipe 73 to the medicine spraying pipe 84, and spray it through the nozzle 85, so as to spray the heart leaf part of the corn. When the hydraulic rod 81 retracts and drives the cross plate 83 to move upward, the valve 75 is automatically closed by the tension of the tension spring 76, and the nozzle 85 stops spraying. Through the continuous retraction of the hydraulic rod 81, the gear 86 and the gear plate 89 cooperate to make the cross plate 83 and the guide frame 87 flip over, and then the cross plate 83 and the nozzle 85 are reset, so that the nozzle 85 faces upward.

[0077] Please refer to Figures 1 to 16 The working principle of the coupling device for farmland soil cultivation and fertilizer spraying provided by the present invention is as follows:

[0078] Step S1, firstly, the device is connected to the external traction mechanism through the traction frame 9, then materials are added to the medicine box 71, and fertilizers are added to the fertilizer hopper 61, and then the device is moved to the corn field where soiling and fertilization are required through the traction mechanism, and the position of the device is adjusted and driven to move by the traction mechanism, and the drive motor 54 and the hydraulic rod 81 are started when the device moves;

[0079] Step S2, the rotation of the driving motor 54 drives the rotating shaft 52 to rotate, the rotation of the rotating shaft 52 drives the discharging impeller 53 and the fourth belt pulley 64 to rotate, the fertilizer is evenly sprinkled in front of the tilling wheel 32 through the rotation of the discharging impeller 53, and the fourth belt pulley 64 drives the two third belt pulleys 63 and the two crushing rollers 62 to rotate through the two second belts 65 when rotating, and the agglomerated fertilizer is crushed by the rotation of the two crushing rollers 62;

[0080] Step S3, when the driving motor 54 drives the rotating shaft 52 to rotate, the rotating shaft 52 drives the two second pulleys 36 to rotate, and the rotation of the two second pulleys 36 can drive the two first pulleys 35 to rotate through the two first belts 37, and the rotation of the two first pulleys 35 drives the tilling wheel 32 to rotate, and the rotation of the tilling wheel 32 is used to cultivate the corn root system;

[0081] Step S4, when the hydraulic rod 81 moves downward, it will drive the two connecting plates 82 to move downward. During the movement of the two connecting plates 82, the two gears 86 will be driven to move downward. When the two gears 86 move to the position of the gear plate 89, the gear plate 89 will cause the two gears 86 to drive the cross plate 83 and the guide frame 87 to flip, so that the spray head 85 is downward, and the hydraulic rod 81 continues to extend downward to drive the flipped cross plate 83 to move downward. The cross plate 83 will press down the valve 75 during the movement, and the water pump 74 will be turned on at this time. The water pump 74 will pump the medicine through the medicine outlet pipe 73 to the medicine spraying pipe 84, and spray it through the spray head 85, so as to spray the heart leaf part of the corn;

[0082] When the hydraulic rod 81 retracts and drives the horizontal plate 83 to move upward, the valve 75 is automatically closed by the extension of the tension spring 76, and the spray head 85 stops spraying. The hydraulic rod 81 continues to retract, and the gear 86 and the gear plate 89 cooperate to turn the horizontal plate 83 and the guide frame 87 over, thereby resetting the horizontal plate 83 and the spray head 85 so that the spray head 85 faces upward.

[0083] Step S5, when the two hydraulic rods 81 continue to extend downward and drive the cross plate 83 to move downward, the cross plate 83 will press the two mobile brackets 41 downward during the movement, and the two mobile brackets 41 are pressed downward, and then the pressure plate 44 is pressed to both sides under the action of the connecting rod 42, so that the soil after soiling is compacted; when the two hydraulic rods 81 retract upward and drive the cross plate 83 to move upward, the telescopic spring 48 is set to make the mobile bracket 41 slide upward on the inner side of the spraying frame 72, and the pressing state of the pressure plate 44 is cancelled under the action of the connecting rod 42, and the cross plate 83 moves back and forth up and down, so that the pressure plate 44 compacts the soil after soiling at a certain frequency, thereby completing the soiling, fertilizing and spraying work during the corn bell mouth period.

[0084] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
